Product introduction: Arduino IIC/I2C interface LCD1602 adapter board without LCD screen There are only 20 IO ports on the Arduino control board. Add some sensors, SD cards, relays and other modules, so the IO ports are not enough. The original 1602 screen needs 7 IO ports to drive. This module we developed can To help you save 5 IO ports, we send arduino function library. Product parameters: 1. Size: 41.5mm(length)*19mm(width)*15.3mm(height) 2.Weight: 5g 3.PCB color: black 4. Supply voltage: 2.5-6V 5. Support I2C protocol 6. With backlight power control, you can set whether to connect the backlight power through the jumper cap. Plug in the jumper cap to connect the backlight power, unplug the jumper cap to disconnect the backlight power 7. The contrast can be adjusted. Rotate the blue potentiometer to increase clockwise and decrease counterclockwise. The potentiometer is designed on the front, which is convenient for customers to adjust freely anytime and anywhere 8. Modules can be cascaded, up to 8 can be cascaded. Modify the device address by shorting A0/A1/A2. The default address of the I2C transfer board is 0x27
